im a volunteer retired fire chief with extensive training and he is wrong about short bursts in my opinion. always point the nozzle at the bottom of the flame and go side to side moving in as close as you can get, NO SHORT BURSTS because when you hit the fire which starts to push the flames back and when you stop your attack by a short burst the fire comes at you again. when using an extingwisher NEVER use short bursts especially in a closed area like a garage. that fire will act like a tiger and when using short bursts the flames CAN ovr take you. full on side yo side at base of flames. do not use 2.5 lb extingusher in garage. it is not big enough to put any fire out in a building. always have at least 2 10 lb extingushers abailable. by doors so if fire is to big you can excape the fire. NEVER, NEVER USE BURSTS, THE FIRE WILL OVER TAKE YOU.
Howard, thank you for your additional comments.
P.A.S.S.
P. PULL PIN
A. AIM AT BASE OF FIRE
S. SQUEEZE TRIGGER
S. SWEEP UNTIL FIRE IS OUT
As a retired fire prevention officer with 30 years experience I agree with you 100%. Also, if you have a big rig rig get a large fire extinguisher that is well made. A 21/2 or five lb extinguisher is not going to do the job. If two extinguishers have the same rating don’t cheap out, buy the more e pensive one. I’ve seen many cheap extinguishers that were next to useless. CO2 extinguishers are all generally well made. ABC rated extinguishers ran the gamut from cheaply made to very well made.
thanks good advice.. he did say that it depends on the fire and the situation.
Best way to do it is empty the extinguisher completely. Just hold the lever until it’s empty whether the fire goes out or not.
A word about CO2 and Halon extinguishers. They are great for extinguishing gasoline or electrical fires but if there is a source of re-ignition available the fire could start right back up where it left off. I came upon a vehicle with a tire on fire. the fire had just started. My halon extinguisher put it out with one shot. Moments later the smoke re-ignited explosively spewing burning molten rubber everywhere. The extinguisher put it out again and again, every time it re-lit. 911 had been called and I could see the trucks coming when it re-;it the last time but the extinguisher was empty. The engine compartment caught fire and the vehicle was a complete loss in less than 60 seconds. I have used dry chemical on an engine fire twice and it worked right the first time. It is easier to clean up powder than a burned car. Once a car fire starts you have only seconds to make a difference.
Co2 is handy for dealing with a runaway diesel engine also, especially if the turbo fails while the engine is on test, Co2 drawn into the intake will drop the RPM instantly and the engine will stall.
Frederickforlife James anything suffocating the engine will do so yes
Never hurts to keep a bucket of sand in the corner of the shop as well.
It's very cost effective and easy to re-charge.
He should have also mentioned that if you have an engine fire, opening the hood can be very dangerous.
That's the part that worries me the most - I'm tempted to get hood pins and remove the stock hood latch. The downside to that is thieves, of course.
shouldnt you be shooting exotic shotgun shells right now?
Jay Leno is coming over and we are going to shoot a giant gummy bear out of his Stutz Bearcat! lol
You would be the perfect guy to shoot the burnout in slow-mo.
i wish neil had gone into ABC or BC what type you want.
Very well done, one that I will share. 45 years in the fire equipment industry and correct videos about portable fire extinguishers are rare.
As a fire extinguisher tech i would use a CO2 or Halon in a closed atmosphere of a computer server room. There's all kind of applications to use a CO2 but mainly in a server room. I would recommend either an ABC class or a BC class using regular dry powder for your vehicle.
must not value your vehicles as the powder in dry chemical extinguishers is corrosive and will eat the paint in time, I PREACH CO2 all the way but with my 40 years as Fire Chief and 30 yrs of extinguisher service guy WTH do I know
Or his life…CO2 or Halon in a closed room is a potential death sentence!
@@phantomcruizer ABC powder is just as deadly in that enviroment also and does not clear out as fast as the CO2 but a 20 yr ext. guy and 40 yr firefighter WTH do I know
When exiting the car with a suspected fire, never forget to turn the ignition off!
In so many of our worlds we have fire safety training ...Its good to see Jay pay attention to this serious issue.
They need to upload a previously made video discussing fire extinguishers. Neil had a gentleman from Amerex join in, I believe his name was Andy, who went in depth with types & kinds of extinguishers. Halotron is an environmentally friendly alternative to halon.
Great information, Jay. Thanks!
Wonderful video. Thanks so much for the info, I was just looking into this the other day with not much success . Your video answered all my questions.
Jay you are a very special person. I only wish more people like you appreciate our troops. Thank you from the bottom of my heart! Also I love your show and look toward to watching it every week. Keep up exactly what you are doing! Be Well Willy
Jesus Christ! Jay is there behind of you a replica of the famous 1954 Mercedes-Benz Renntransporter? FANTASTIC!
Really good to know that we all need to look into these things too.
Thanks
Jay: I just watch the video clip of you giving Cpl Laberge the Hellcat. Outstanding!. I almost cried. Thank you for the effort.
Very informative, didn't know this about fire extinguishers.
Good to know, thanks Jay!
Nice...great information...learned something
I LOVE that element fire extinguishers shown earlier.
I even have one on the side of my KTM 990 Adventure.
Some cars are so troublesome you can only hope they DO catch fire!
Great info!!!!
When in doubt always ask a PRO who knows about extinguishers and how to use them. I am that PRO. Chem clean/chem guard is a great new type of FF agent. Expensive but offers a clean end result as compared to foam and chemical extinguishers. Cold fire is great too!!! Co2 has been used for many years and has its advantages for effective fire knock down with class B & C fires. BC /ABC or PK( Purple K) are 3 chemical type agents that work well when used correctly for their ideal applications. In all the many car/vehicle fires that I have put out ABC was what I used. Small engine fires that are not yet fully involved can be dealt with by using Co2/ Clean guard or halon 1211 if still available. I love Halon 1211. Fire gets knocked right out and no damage to engine or area exposed to the flames. I encourage all car/vehicle owners to have an extinguisher or 2 in their vehicle along with having some in the home.
2.5lb-5lb size are good for small early stage sized fires but in my experience with many fires it was a 10lber that saved the day. Better to have too much than not enough. The next MOST important step is to get trained on how to use the extinguisher! I have taught hundreds of folks and it's amazing yet tragic to see what happens when the real deal shows up. Fear being the main culprit that walks hand in hand with the lack of knowledge of what to do and how to do it. When in doubt 911 first if possible & then GET out and wait for the FD to arrive and take care of business. I have toured Jay's shop and awesome car museum and he has done VERY well in making sure that fire fighting equipment is available for staff to use in case of trouble.
Thanks Dwight, in my 45 years in the industry a few changes also, from soda acid to a return of a ball holding extinguishing material thrown into a fire, and small watermist droplets from a thrown canister. Early on I had a soda acid explode when activated because the hose was plugged with dry chewing gum. Seems the lab testing did not include testing the hose to break before the container exploded.
A CO² extinguishers do have many limitations, dispite leaving no harmful residue and it important to understand these limitations. CO² can be very effective on fuel, oil and electrical fires, but because they work primarily by removing the oxygen rather than removing heat, their effectiveness is severely reduced in windy conditions, and ineffective on class A fires because the glowing embers tend to cause re-ignition as soon as the CO² dissipates, therefore a CO² extinguisher cannot obtain an A rating.
Halon was banned from production on January 1, 1994 in accordance with the Montreal Protocol, due to the severe ozone layer potential, nonetheless it happens to be one of the most effective clean agent extinguishers on the market, with a BC rating, while larger units can also have an A rating
Halotron I is a replacement for Halon and is much safer for the environment, although slightly less effective per volume than halon 1211. Like it predecessor, Halotron I is a clean agent with a BC rating; but 11 and 15.5 lb units also get an A rating as well. Discharging a stream of vaporizing liquid, it works by cooling and removing oxygen.
Thanks Jay for great segment and tribute to the soldiers. Also, thanks for your generosity to the USO. Love the cars you profile.
I am a 70 muscle car lover from way back. My first car was a Plymouth GTX 440. Do you have one?
very informative
thank you
Great stuff, I love to see these sales guys do their thing. Especially since the products that Jay allows on the show seem to be top notch. Thanks for all the tips!
Great video, very helpful.. 🏁🏁🏁🏁🏁👻🏁👍🏁🏁
I have the extinguishing system similar to nascar for my SRT..Not that I've had any problems but you always need to be ready especially when you're boosted and temps get hot. Floods the whole engine bay with the push of a button.
Jay, could you do a show on early tractor trailer trucks? I drive semi's for a living and thought it would be an idea for your show. Thanks for all the great cars. I loved the 1950 Nash Ambassador.
Use PASS
Pull the pin
Aim at the base of the fire
Squeeze the handle
Sweep back and forth until the fire is out
I keep a foam extinguisher in my car, had to use it once on a car that caught fire while I was driving it. Save me and the car.
The foam is fantastic, as it dries out and doesn't contaminate anything.
Sorry....retired firefighter paramedic of 27 years...just some thoughts. First off...you should have an extinguisher in ALL vehicles regardless of age. Fires occur in all vehicles of all ages. A properly sized and rated extinguisher in all cars, trucks, boats, planes and atv's. First off its in case your vehicle starts on fire. Secondly to aid someone else who has a car fire. Correctly rated and sized....A, B, C, D and the units measured usually in pounds. Many have multiple ratings in ABC, BC etc. This is so you have the right agent for the materials burning and the size/potential of the fire. Be careful of cheap box store extinguishers and new age extinguishing agents. Some agents will put out a fire but may release toxic fumes when they hit hot metal. To get something that will work when needed...it will cost a couple bucks, well worth it. Consult your local fire department or fire extinguisher/fire safety distributors to get the right extinguisher(s) for your scenario. Also.....in 99.99999% of fires 1. Evacuate the building/vehicles 2. Call 911 3. From a SAFE exterior location with the proper extinguisher it MAY be possible to knock the fire down. ("Prior to the fire" have the proper equipment that is routinely checked and maintained and have the training on how to use it as well as an evacuation plan)
Co2 extinguisher is super good at cooling a 12 pack of beer too.
OMG!!! you have to do a segment on that Mercedes Car Carrier behind you. Please please please...
The biggest problem with the CO2 fire extinguishers is just how _expensive_ they are compared to other options. That 5 pound CO2 model costs $241.
And recharge is not "a few bucks" [as he said] either.
Good
One thing they failed to mention in the video is that CO2 is not rated for a class A fire so if plastic, paper, or clothe catches fire a CO2 won’t be good.
FYI, CO2 is only listed for BC fires. Not used for ordinary fires such as wood and paper.
I see the Red Corvair is being worked on.
Hey Jay nice video, but in the real world a 2 1/2 lb CO2 unit isn't going to be much help with an engine fire on a breezy day, and won't be of any help at all on an interior fire like wiring or upholstery since it isn't rated or effective for class A fires. If you want to buy a little CO2 or halon unit as your first line of defense because it leaves no mess, go right ahead - but also carry a 5lb ABC dry chem unit with a hose, so you can poke it up under the dash or under the seat if needed.
Pay attention to the UL ratings, most 5lb ABC dry chem extinguishers these days have a 40-B rating, while your 2 1/2 lb CO2 is rated only 2-B and a 2 1/2 lb halon is rated 5-B. The ABC unit has a much higher class B rating and also is UL listed for class A fires like upholstery, which the CO2 & halon are not. I'd rather have a repairable car coated in dry chem, then a pile of ashes & melted plastic.
But it's good advice to AVOID the junk extinguishers with plastic valves sold at discount & big-box stores. An extinguisher is like a parachute, pay for quality up front because you may not get a second chance. I agree that Amerex is as good as it gets, you can always buy one from Amazon if you can't find a fire equipment dealer locally.
you are a sensible person.
5:17 One word of warning, whenever you fire a fire extinguisher, never ever aim it at the camera man.
Amerex 2.5lb are going for approximately $160.00 . Still cheaper than a new car.
No cameramen were harmed in the filming of this video.
I'll be putting my fire out before I call 911. They are minutes away when seconds count. Same reason I wouldn't call a cop until I was safe, if someone was kicking in my door.
METAL!
It would be better to have a firefighter or someone from the extinguisher industry speak to the issue of extinguishers and car fires. Even Jay seemed to be more concerned with fighting the fire than getting the passengers out or dialing 911. Howard Young seems to give good advice, but even he gets a little wishy-washy - to sweep or to burst, that is the question I'm still not sure about, that and do you open the hood or not? BTW the best protection against fire damage and loss is insurance with a rider that specifies the replacement value of the vehicle. Otherwise you might get $200 for your wrecked one-off Johnnie High Schooler DNA-Special Back-SeatMobile which has documentation that it was used in the indie film "Paris Hilton Slept Here, and Did Other Stuff, Too!"
I wish jay would make a video series and just show his entire car collection
Where in the world did you find the 2.5 lb version?? I cannot find it anywhere! Not even on the Amerex website!
+Dave They are very rare. For the price you're better off getting the five pound.
To reason why the nozzle is plastic if you ever used a computer duster you will notice the can gets very cold and freezes your skin to the can... same problem applies when you hold metal when expelling C02 last thing you want is to have frostbitten fingers
You can use the Co2 to put out flaming LED Ceiling lights you were selling. Oh wait, I see none of them in your videos.... Still the old fashioned sodium vapor and fluorescent tube lights in use.
You know how big his garage is right? Maybe he installed the LEDs in his other 3 or 4 buildings.
How do you know that? Got a link?
He has led lighting in his garage, watch his videos.
The LEDs are right in front of you. They are in the fluorescent fixtures. Easy way to tell is to look at the fixtures. The old tubes throw light 360 degrees so the fixtures are brightly lit. LEDs throw between 90/180 degrees (120 is real common) so the fixtures are not lit up, and you can also remove any reflector shrouds.
As for the large units that he did a segment on recently, those are in the "storage" shop. The one where he parks all the restored cars.
This is because the workshop had already been rewired to use fluorescent lighting but the other building wasn't, there were still HPS lighting in there.
As for size - 2 buildings, that share a wall, approx 17,000 SF
I'd look up Blue Spectrum High Energy Visible light (HEV), and how it has scientifically been found to contribute to AMD or Age Related Macular Degeneration. LED generated light lives in the peak of that spectrum of light ... time to rethink that LED upgrade in your home/office.
Is an engine on fire salvageable anyway? I just bought a BC extinguisher. I read that ABC extinguishers are corrosive to the car. Is it worth it to buy the CO2 extinguisher or is a fried engine going to have to be replaced anyway?
So what make of fire extinguisher is this US made? How about a link to this web sight he mentions?
Jay, please do a couple episodes on suppression systems. They have them for race cars, but I don't know where to get one. I would appreciate it if you would do a couple - low, mid, and high end. I would like to get a system for my car and pickup truck, preferably with a electric cutout switch. If something happened, it would be nice to pull one knob, and hopefully save my vehicle. I imagine that, even though it may stand out in one of your classic or custom cars, you too could cruise that much easier with the thought that it would be there if you needed it. Besides, if it is a engine fire, that being able to activate it quickly, and without risking opening the hood would not only help protect property, but your viewers as well.
Thank you.
Made my own fire suppression system using some old NOS fogger nozzles plumbed them to a Halon system used one time in the shop had engine fire slammed the hood and pushed the button to the solinoid that opened that bottle, fire out
The issue with car fires is usually Class B (gasoline or Diesel). Foam has a much higher rating for Class B fires. CO2 5 lb is 5 vs 40 for 5 lb foam.
Hey jay, has ssc given you your tuatara yet?
I recommend a Halon, Halotron or FE36 Fire extinguisher.
Neil is a cool dude
There is no significant cooling effect using CO2 on the fire. However, holding the horn of one shown can result in frostbite to your hand.
What If I use my paintball gun?
I think less expensive for small fires! Doe that 2 1/2 pounder is best choice!
Does Amerex still make this 2.5 lb Co2 extinguisher? Not finding one. I see 5lb Co2 around the web. And what is the part# for the Bracket for this model 320?
Nope. They probably realized how ineffective such a small CO2 extinguisher would be.
Yes they still do, their main market is the military because it is a drop-in replacement for the vehicle Halon 1211 units that are being phased out. So, you'll have to order one through an Amerex distributor. The model 320 is the civilian version which comes with a wall hook, the model 320NM is a nonmagnetic version for use in MRI rooms and also comes with a wall hook, the model 321 is the military version which comes with a vehicle bracket which can also be ordered separately, the bracket is model 896. Hope this is helpful.
It should be illegal to sell rubber fuel hose which is 30R6 rated, because it is degraded by ethanol, People need to fit 30R9 or later which is Ethanol Resistant.
took 3 minutes to get to THE POINT............ scheech, Old Dudes
Good Info, Thanks
Halon works Good
One thing I have see during life safety training. Some people will aim the extinguisher at the flames instead of the thing that is burning. Shoot at the object that is on fire!
How does one refill a fire extinguisher? Go to the local fire dept? If the gaskets are compromised do they switch those out too?
Ask the agency doing the service work on an extinguisher for a copy of their liability insurance. Quite often their attorney will suggest they either get the insurance or cease the activity.
You take it to a company licensed to deal with fire extinguishers.
I agree. There are some dangerous posts on youtube about misuse of extinguishers. There is one from a fire district that offers tag and seals for doing your own annual maintenance. Recently a fire extinguisher manufacturer removed the schraeder valve from its water units to help prevent the recharging by untrained persons.
What was the blue Mercedes in the background
I saw a guy get shocked from a 110v outlet. Fired one into a fire and in the fire was electric outlet. He let go of the bottle pretty fast.
was it a co2 extinguisher?
Why anyone still buys these old bricks is beyond me...Check out Stop-Fyre for a real fire extinguisher. On a side note, how does this guy go on Jay Leno's Garage promoting his fire extinguisher and not know how much it cost to refill?
Because it is way more than "a few bucks" as he said. BTW Stop-Fyre has been out of business for decades.
Halon is awesome, no mess, knocks it right down. But if it's rubber or something that hold lots of heat, the halon could be an issue. "Available" until 2025" Haha, they said worse in 1990 when "they" caused the price of Halon to sky rocket. I made $15,000 in one day on Halon! Then someone brought it over the great lakes from Canada, then China imported it and the price went down. (Halon is use on submarines) Another time I was in a room when a friend accidentally discharged a 500lb bottle in a computer room. I ran out and came back in 15 seconds later, my friend was still trying to "put the tooth paste back in the tube". The room became very cold and smelled like ozone. But nothing happened to us, no ill effects, nothing. (You might remember "Terminator" where Arnold says +/- "watch out , that's Halon, it's toxic..." nonsense.,,,) Lastly: I had a dry chemical ext' in the trunk of my 1959 Corvette. It bumped into something and self discharged. I spent the eons trying to get that crap out of my trunk.
Ahh! Portable extinguishers Halon 1211 or Halotron 1and other clean agents. Automatic suppression systems may not be Halon 1211 or Halotron 1 but Halon 1301 or other less toxic, toxic in the area of breathing air being displaced.
once used a pick and a garden hose to put out a car fire. The older man went inside to do something ...for just a second...and he leaves ft his car running on a very hot day. I was the only one to see the car smoking. I grabbed the neighbours pick and garden hose whilst he went to call 911. Three holes in the hood and a spray of water over the burning words and grease was enough to put out the fire.
Yes, I know water and oils and gasoline don't work well together when combined in a fire, but the smoke told me what was burning.
The fire truck and Police arrived. the old man was woken up to see his newly air-conditioned car. It was repaired.
Aim at the base of the fire !
Call a local extinguisher company and ask about training.
You don't want to learn on your classic car.
We haven't seen a decent car for over a month now. Come on Jay
Co2 is also not a gas. when under pressure it is a liqued form.
***** exactly
***** Dry ice is solid CO2, under pressure it is liquid, and a gas at room temperature. Thank you.
***** How is it "normally" a gas if it has 3 states of matter? It is more abundant in gas form, but in this case it is a liquid, and boils to a gas when released into the atmosphere. So back to your original statement "Like any gas under pressure, carbon dioxide is indeed a gas man." which is wrong.
Sun Tzu are you familiar with phase transition? gas can change to liquid solid or plasma depenting on pressure and temprature and what defines a gas or any matter really is the form it has at standard contitions all matter change but you wont say for exmple tha water is a solid or a gas cause its liquid at standard condition
Mohamet Gabr " when under pressure it is a liquid form" -Correct
"Like any gas under pressure, carbon dioxide is indeed a gas man."- A gas is a gas under pressure? Not exactly, "carbon dioxide is indeed a gas man."- Depending on circumstance.
I think you missed all that.
you bring Bill Cosby to mind and his cobra snake
One thing, aim at the base of the fire, not at the flames or you'll miss the source and the fire continues.
i know this is a dated film but i cant believe you guys dont know about cold fire suppressant check it out
Thanks for the reminder. Such an evolving industry both with dedicated research/testing, and some just dedicated to cash flow.
What does he mean by it has to be recharged???
Like if you empty a bucket of water, or a coffee mug.... if you want it to work again it must be refilled [recharged].
This must be the last episode of Skinned Knuckles as there hasn't been any new once since. I wonder what happened...
Dry Powder Agents corrode electrical and if sprayed on engine components the agent will slowly work itself through the wires and reach the PCM where it will destroy it.
Where, of course, the fire will do no harm at all.........?
His point IS use a different fire extinguisher than dry chemical to preserve your cars electrical system. 😎
ok, lots of talk, get to the point.
i put a halon in my 15 Z06. it is half the size of those. fortunatly for me over the 48 years ive driven ive had no fires but have put out 2 car fires.
Always use your fire extinguisher first. CO2 is conductive. Halon is great. But get purple K. It's messy, but at least you can clean your car instead of shoveling the remains up.
How does CO2 get a C rating if it is conductive?
@@alvagood2693 Co2 is not conductive. The rumor started before the hoses were checked for electrical continuity, and the flowing liquid/gas would generate static electricity, and sometimes cause a shock. Yes, happened to me, hence the research I did.
Ethanol even destroys Viton rubber over time a huge problem with seals on Britbikes. As if they did not have enough leaks already!
A couple of buckets of sand in garage you can lift and spread, oiley rags also can ignite without warning if in piles.
How can halon be banned it's in the terminator film for the computer labs!
because of global warming nut jobs. That's right because of something that doesn't even exist an effective life saving method of fire control is banned.
yeah that global warming feels great right now, that's why there is 8 feet of snow in Buffalo and it's 25 degrees outside today, I think I'll go put on some shorts and some sunblock.
I think first responders also suffocate if they enter a room with Halon as it evacuates a lot of oxygen. Banned because of the massive ozone damage from high altitude nuke tests and other factors other than the CO2 myth. Like Hawaii right now is not belching a ton per second that and I think the sun heats the earth and mar's ice caps LOL!
Halon can no longer be manufactured (like R12) because of the tree huggers.
Halon works by breaking the chemical reaction in the fire itself. BUT halon in a portable unit is not a good idea. Halon disperses rapidly so you really want to use it in confined spaces, sealed rooms and such. For that use a portable unit won't carry enough agent to flood the room.
In open fires Halon may stop the fire BUT because it does nothing else (no cooling or retardent properties) the instant it drops below 8% concentration the fire can relight off heated surfaces, In a closed room the halon will kill the fire and you leave the room closed until it cools down OR until you can dump a cooling agent into the room.
@@Hoverbot1TV Halon will not suffocate even in a [properly sized] total flood system. Hence its advantage. CO2, to be effective, MUST displace enough oxygen to stop combustion... which also stops breathing.
that's better
Did you run out of cars? I think we wanna see them rather than some Bosch dudes or fire extinguishers
He never explained why the nozzle isn't made of metal. He started to, but then he didn't finish it.
He did, just not very clearly. It's because metal would get extremely cold and burn your hand.
The reason it is not metal is not only because the discharge is so cold but the velocity causes static electricity. You would get zapped if it was metal. When you inspect a CO2 extinguisher you should always check the plastic portion for cracks. Getting zapped hurts!
That is a really cool fact, thanks for sharing.
mrjost55 Motorphoto509
You are both right :) It's because of temperature and static discharge... although the plastic ones still give off a discharge it is much less intense compared to a metal nozzle. But freezing is the most important factor... metal could burn your hand when it's too cold.
BTW... just don't use a powder or chemical extinguisher and you're good. Powder makes a mess and chemical will eat into the electronics...
In fact very early CO2s had horns made of metal. They are made of plastic so that they will not conduct electricity if accidentally touched to live equipment. The plastic horn will get just as cold, which is why you should NOT hold them on the smaller units, and only use the insulated handle on the larger units.
The reason dry fire extinguishers are good for cars in they won’t burst in a hot car like the gas ones do. No???

Halon or Halotron is the best for cars
Down side of CO2; must be very close to a small fire to do any good. Once agent dissipates, you can have a re-flash. Cylinder is high pressure and must be hydro tested every 5 years. There is no good replacement for halon yet.
It's nice if you can get the fore out with CO2 but you absolutely right you need to get close. Any wind significantly reduces the effectiveness.
In addition to your halon comment, the replacement of halon 1211 with Halotron 1 is a reduction in capability. It takes more Halotron 1 than Halon 1211 to get the same fire test ratings. Halotron 1 cools the burning situation whereas Halon 1211 inter reacts with the burning process.
you brought up the fact that the new fuel eats the fuel line and nd I know that there are rubber lines suitable for the new fuel why don't you do a video about updating the lines on older cars
The government wants the older cars off the road. Burn baby burn they cry
Co2 is clean but has limited fire fighting capacity compared to a dry chemical extinguisher. As demonstrated the Co2 disperses quickly and outdoors that can be a problem. Co2 can penetrate through the radiator or other vents as well can be used to flood behind the dash if needed. Co2 is more costly to refill and maintain its a high-pressure cylinder that needs to be hydrostatically tested every five years if you’re going to keep up the maintenance, its about a 800 psi cylinder. Don’t buy store-bought extinguishers they are mostly junk and undependable, Amerex, Sentry, and the heavy duty Badger extinguishers I wore the few extra dollars to buy them. What I said about Co2 holds the same for Halon and Halotron. Co2s can be test fired without usually leaking down but need to be weighed to confirm that, the full and empty weight is on the extinguisher.
I used to believe that CO2 would be effective thru the radiator. An actual firefighter told me it will mostly build up 'snow' and not pass thru the radiator, where dry chemical will. Sure enough, when I became a FF I found that to be true.
So farting on the flames is no good? Not environmentally friendly?
methane gas burns.. Fart in the gas tank if you must.. doubles your miles per gallon if you eat beans
what if my passenger is playing bad music, can I leave em in the car then?
too bad there's not a demonstration in the vid.
Sorry CO2 works very bad especially outdoors and in class B fire with high pressure vapor fuels like gasoline. You cannot put out a fire in a car engine with CO2 even with a 10lbs if outside and if gasoline is involved with some quantity. ou will have fire spread every where.
Hallon is very good but there is also an alternative FE-36. On US they are made by ANSUL. It is good to be used inside a car in case of a short circuit fire in the dashboard but don't forget to disconnect battery. It is clean no mess but they are more costly.
For car fires in general I recommend to have in a car a PURPLE K powder fire extinguisher. They are very fast in knock down a fire and not corrosive. To avoid reignition also recommend to use a foam fire extinguisher after the Purple K that way no reignition possible. In US AMEREX makes superb quality fire extinguishers and the foam ones are easy to refill by yourself there are some videos here in you tube to see how.
Stay out of CO2 it is a very high pressure fire extinguisher and in case it explodes by excessive heat in the Summer ( besides it has a safety valve) or in a car crash it is like a grenade the contents CO2 will expand violently. I am not saying it will always happen but it may happen. I have seen a few accidents with CO2 fire extinguishers not nice at all.
Some of the newer water type extinguishers no longer have a Schrader valve for pressurizing these type of extinguishers by those not having the tools to service extinguishers.
Two problems with co2 #1 extreamly high preasure in the cylinder if you crash I could explode causing about as much damage as 3 or 4 frag grenades #2 not only is it difficult to put out fuel with them it may actually spread the fire if used improperly
